John Lancaster
Lisvane & Thornhill
Group Leader
07779 975500
I was born and raised in Lisvane, attending Lisvane Primary and Llanishen High schools. I am proud to have sat on the Board of Governors at Llanishen High since 2018. I have always been interested in local issues, including joining the Reservoir Action Group which successfully campaigned against the development of Llanishen and Lisvane Reservoirs.
In 2017 I was honoured to be elected to Cardiff Council as a Councillor for Llanishen and Thornhill. When changes to ward boundaries were implemented in 2022, I was re-elected to the new ward of Lisvane and Thornhill. I am simultaneously both proud and humbled to be able to represent the community in which I grew up.
My background is in Environmental Sciences, which I put to good use as a member of the Council’s Environmental Scrutiny Committee. I consistently challenge the Council over a wide range of areas including recycling, public transport, the Replacement Local Development Plan and, most recently, the proposed Workplace Parking Levy. My experience of increasing housing development in Lisvane highlights to me the importance of getting the right infrastructure in place to support our expanding communities, and also of protecting the remaining greenfield space we have left in Cardiff.
In 2024 I was elected by my Conservative colleagues to lead the Conservative Group on Cardiff Council. Since then, we have achieved several wins, including: the Council finally agreeing to implement year-round collection of garden waste; forcing the Council to drop its plan to remove litter bins from our streets; the reintroduction of free parking in municipal car parks; and forcing Labour to drop its intention to impose a Congestion Charge on Cardiff's drivers. I am also proud that each year, we propose an alternative Budget that reflects our Conservative values: lower Council Tax, more focus on frontline services, and greater efficiency of public spending. These are the things which help drive me in my service to you, as a Conservative Councillor in this great city of ours.
